Abstract: A corona discharge (24) ignition includes an electrode (38) emitting a radio frequency electric field and providing a corona discharge (24) to ignite a combustible mixture. The system includes a controlled high voltage energy supply (52) providing energy to a main energy storage (28) at a main voltage. A fixed high voltage energy supply (54) provides extra energy to an extra energy storage (26) at an extra voltage, which is greater than the main voltage. While the corona discharge (24) is being provided, the energy of the main energy storage (28), but not the extra energy storage (26), is provided to the electrode (38). When the corona discharge (24) switches to arc discharge, the extra energy of the extra energy storage (26) is provided to the corona igniter (22) to enhance the arc discharge and provide reliable ignition until the corona discharge (24) is restored.

Abstract: An igniter (20) includes an outer insulator (24) formed of an outer ceramic material hermetically sealed to a conductive core (26). The conductive core (26) is formed of a core ceramic material and a conductive component, such as an electrically conductive coating applied to the core ceramic material or metal particles or wires embedded in the core ceramic material. The conductive core (26) is typically sintered and disposed in the green outer insulator (24). The components are then sintered together such that the outer insulator (24) shrinks onto the conductive core (26) and the hermetic seal forms therebetween. The conductive core (26) fills the outer insulator (24), so that the conductive core (26) is disposed at an insulator nose end (34) of the outer insulator (24) and the electrical discharge (22) can be emitted from the conductive core (26), eliminating the need for a separate firing tip.

Abstract: A spark plug includes at least one electrode having a sparking end. The sparking end is formed of a high temperature performance alloy including chromium in an amount of 10.0 weight percent to 60.0 weight percent, palladium in an amount of 0.5 weight percent to 10.0 weight percent, and a balance substantially of at least one of molybdenum and tungsten. The sparking end presents a spark contact surface, and at a temperature of at least 500° C., such as during use of the spark plug in an internal combustion engine, a layer of chromium oxide (Cr2O3) forms at said spark contact surface. The layer of Cr2O3 protects the bulk of the sparking end from the extreme conditions of the combustion chamber and prevents erosion, corrosion, and balling.

Abstract: A spark plug having one or more electrodes at least partially fabricated from an aluminum-containing Ni-based alloy. The alloy is a volume-stable alloy that includes a Ni3Al precipitate in a γ′-phase distributed in a Ni matrix γ-phase. The precipitate is formed in the alloy prior to the alloy being used to fabricate electrodes and thus prevents additional Ni3Al precipitate from being formed in the alloy once in service in a high-temperature environment. This, in turn, prevents a volume decrease of the alloy that may lead to an increased spark gap and spark plug malfunction. The volume-stable alloy may be made by solution treatment, quenching, and heat aging of a Ni—Cr—Al—Fe alloy.

A conductive shell surrounds at least a portion of the ceramic insulator and a ground electrode having a ground electrode sparking surface is operatively attached to the shell.
